anyone ever use one of these?

I want to add more filtration to my 300G I am currently running about 1800gph thru my wet dry but after a year and a half of running, the past few weeks the water has not been as clear as usual. I'm thinking of running one of these with around a 700-900gph pump. Opinions please.

Maybe try adding some more bio media to the sump and adding another 1800 gph pump.
